Hey B... did some searching and not exactly sure what you are looking for.
But this site: http://www.newhomesource.com/search/...8&srchtype=map
Seems to map them out no?
I could not find Alter Parkway, just a John Wayne.
So for the first 2 you will want to go to the Smith Enke community first. These could be on the NW, SE and SW corners as there is undeveloped land there. Your second stop will be Honeycut. And it will be on the NE corner of that intersection.
That first link I gave you will give you a better idea of what developments you want to go look at.
Couldn't go more indepth with just the major cross roads.
Good luck and try to get in on the first phase! Even better if they have NO models and just a portable on the lot as it's the cheapest.
